Price Lists, Catalogues, &c. -- From Messrs. Joseph Bourne & Son we have received an illustrated list of stoneware, insulators, battery jars, &c. The pamphlet is very neatly set out, and there are a number of fairly good illustrations. Messrs. Bourne have recently succeeded in perfecting the process of threading the bolt-holes of stoneware insulators, so that they can be fitted perfectly with screw-bolts of either metal or wood. · ·
